OK so everytime i turn on the gun and i try firing, it shoots without the air anything, you know like if you turn on your gun and if you fire the gun without a tank it makes you know the sounds as if the gun was shooting paintballs. Well, i tryed doing that but after the first 2 shots its just stops working. Is it because its not that charged or is the board fried? Also, when i turn on the gun, the bottom light starts blinking red? what does this mean?
